SPECIFICATION forming part of Letters Patent No. 272,137, dated February 13, 1883.

, Application led October 4, 1882. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. HEERICK, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Goal-Forks; and I hereby declare that the following isa full, clear, and exact desciiption thereof, reference being had to the accompanying drawings, which form a part of this specitication.

Thenature of this invention relates to certain new and useful improvements in devices for sustaining coal in the magazine of a stove when it becomes necessary to remove the dbris of an exhausted fire from the grate and I5 reypot below.

The invention consists in the peculiar con.- struction of a manifoldtined fork and the V method of securing the same in place at the bottom ofthe magazine.

zinc ofi-a. stove, detached and partially broken out to show the attachment ofthe fork thereto. Fig. 2 isl a perspective view of the fork detached.

ln the accompanying drawings, which form a part of this specification, A represents the magazine of astove, such as is ordinarily employed in cylindrical stoves, adapted to burn coal at the base ot a column. Itoccurs, by ac- 3elll cident or carelessness, that sometimes the re upon the grate and in the tire-pot, which is always situated below the discharge end of the magazine, becomes extinguished, while the magazine remains full, or partially so, of unconsumed fuel.

B represents a forli, made preferably in the form shown, provided with a handle, a, upon which two ears, b, sustain a cam-lever, o. TheV fork is also provided with two resistance-lugs,

"4o d, as shown, although one of these lugs might Figure l is a'perspective view ofthe maga-` combustion chamber at the bottom of the magazine through the coal, until the resistance-lugs pass the wall ot' the magazine, when slightly elevating the handle of the device carries such resistance-lugs againstthe inner Wall 5o of the magazine, and the cam then being thrown down toward the handle locks the device in place with sufficient force to sustain the weight of the coal remaining in the magazine. I am avare that a disk or shovel adapted to close the lower end of the magazine has been used for this purpose, such shovel being provided with hooks to engage with lugs cast upon the magazine; but difliculty has been found in the use ot' such shovelrin forcingit 6o through the coal and in securing it to the magazine after the shovel wasin place. Hence, fl

do not claim any portion of that invention.

In place of the cam, its equivalents-like a Wedge or screwmay be employed to compel the frictional resistance necessary to secure the fork to the bottom of the magazine with-Vv out departing from the spiritot" myinvention.

I am aware of the Patents Nos. 148,855 and 225,597, and lay no claim to the devices therein shown.

`What I claim as my invention is- 1. A device adapted to retain coal in the .cylinder, provided with a resistance lug or lugs constructed to enter the cylinder below 7.5 its bottom and bear against the inner edge thereof', anda clam ping device adapted to bear against the outside ot' said cylinder and hold the cylinder between the clamp and lugs, substantially as described.

2. A fork provided with lugs d d, :adapted to bear against the inside ofthe cylinder, and the cam-lever c, constructed to bear ou the Outside thereof, all constructed and arranged substantially as described, and for the purpose speci- 8 5 GEORGE W. HE'RRIOK.
